WELLINGTON RANDALL, OF VARNER, KANSAS.

i DERRICK APPARATUS.

Varner, in the county of Kingman and State of Kansas, have invented certain new and useful Improvements 1n Derrick Apparatus,

of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to grain or strawl throwing machines and has for 1ts obgect the production of an efficient carriage which is adapted to travel upon a throwing beam of a grain or straw throwing machine.

Another object of the invention is the production of an ecient carriage for supporting the several operating cables adapted to be used in connection with a grain or straw gathering apparatus.

With these and other objects in view this invention consists in certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described and claimed. l f

In the drawings: Figure 1 is a central longitudinal section of the apparatus. Fig. 2 is a section taken on line 2-2, of Fig. 1. Fig. 3 is a central longitudinal sectional view through the carriage traveling upon the lifting beam.

l By referring to the drawings by numerals, it will be seen that 1' designates the body of the carriage which is supported upon the wheels 2 which wheels are preferably made small so as to have the body of the carriage 1 to rest close to the ground. The operating mechanism for the crane 3 is formed upon the body 1, and a vertically extending partiy, tion 4 is formed upon the body 1 to prevent the grain or straw carried by the body 1 from coming in contact with the operating or controlling mechanism.

The crane 3 comprises a standard 5 which standard is rotatably mounted upon a platform 6. Awheel 7 is formed upon the standard 5 and over this wheel 7 passes a belt or cable 8 which cable or belt in turn passes over an operating drum 9. It will, therefore, be seen that by the rotation of the drum 9, the standard 5 may be swung or p rotated to the desired position for loading the grain on taking the same from the eld. A bracing frame 10 is carried by the body 1 and is provided with a forwardly extendi Specification of Letters Patent.

l ing upper end 11 which surrounds the standard 5 for eiiiciently bracing the same intermediate its length. i

A drum supporting frame 13 is carriedbv the body 1 and upon this dr-um supporting frame are 'mounted the drum 9 previously mentioned and also the carrier controlling drum 15 and the hay fork controlling drums 14 and 14a.

The crane arm 22 is pivotally connected to the standard 5 as'indicated at 23, and may -be formed in two sections so as to allow the same to be folded when it is so de sired for the purpose of conveying the crane from place to place. A supporting or bracing cable 24 engages the upper end of the standard 5 and also engages the outer end of the crane arm 22 so as to efficiently support the outer end thereof. The pulley 25 is carried upon the outer end of the crane arm 22 and the primary carriage controlling cable 26 is carried over this pulley 25 and also travels over one of the pulleys 27 carried at the upper endtof the standard 5.

Two pulleys 27 are carried by the upper end of the standard 5, the cable 24 passing over one pulley and the cable 26 passing over the other pulley so that these cables may be independently operated without causing one pulley to frictionally engage the other pulley and have a tendency of wearing the same out. The cable 24 passes over one of the pulleys 28 and is then passed around and secured to the drum 15a. The cable 26 also passes down over one of the pulleys 28, and from there is wound varound the drum 15. .The-auxiliary carriage controlling cable 29 passes longitudinally of the crane arm 22 and over the pulley 3()k and from there over one of the pulleys 28 and then is wound around the drum 15 in the opposite direction to the rope 26.

A carriage 31 travels upon the crane arm 22 `and may be adjusted to any position along the crane arm by means of the cables 26 and 29. This carriage consists of a pair of parallel longitudinally extending members 32 which are connected at each end by means of the transversely or vertically eX- tending members 33. Rollers 34 are carried by the carriage so as to travel upon the upper and lower faces of the arm 22. Pulhay closing cable 87 of the hay lifting fork, whereas over the pulley 35 passes the opening cable 38 of the hay lifting fork. These cables 37 and 38 pass longitudinally of the crane arm 22 and over the pulleys 30 and the cable 37 is wound around the drum 14, the cable 38 being wound around the drum lila. A hay lifting fork is suspended from the carriage 3l by means of the cables 37 and 38 which are adapted to operate the hay lifting fork. An arm 53 is carried by the carriage 3l and this arm has iXedly secured thereto one end of the weight sup. porting cable 54. The cable 54 supports an i eqnalizing weight 55 and this weight passes over the pulley 56 carried by the end of the arm The opposite end of the cable 54 is connected to the head of the hay lifting fork for the purpose of constituting a support for the hay lifting fork and relievingi the weight from the cables 37 and 38.

Having thus described the invention, what is claimed as new, is

A carrier comprising a plurality of parallel members, `a carriage slidably mounted upon said carrier and provided with a plurality of spaced rollers working upon said parallel members and engaging the upper and lower faces thereof, said spaced rollers provided with flanges upon each side thereof for preventing the lateral displacement of said rollers relative to said parallel members, and cable guiding pulleys interposed between `said rollers for allowing the cables passing thereover to pass between said spaced parallel members.

In testimony whereof I hereunto aiix my signature in presence of two Witnesses.
